1. Materials By Design: Metals And Metal Alloys Materials by Design. Metals and Metal Alloys. Many metals and alloys have high densities and are used in applications which require a high massto-volume ratio. http://www.mse.cornell.edu/courses/engri111/metal.htm

Metals and Metal Alloys Metals are elements that generally have good electrical and thermal conductivity. Many metals have high strength, high stiffness, and have good ductility. Some metals, such as iron, cobalt and nickel are magnetic At extremely low temperatures, some metals and intermetallic compounds become superconductors Shape memory alloys Video clip: Microsoft Video for Windows AVI (116 kB), Apple QuickTime (112 kB) What is the difference between a metal alloy and a pure metal? Pure metals are elements which comes from a particular area of the periodic table. Examples of pure metals include copper in electrical wires and aluminum in cooking foil and beverage cans. Metal Alloys contain more than one metallic element. Their properties can be changed by changing the elements present in the alloy. Examples of metal alloys include stainless steel which is an alloy of iron, nickel, and chromium; and gold jewelry which usually contains an alloy of gold and nickel. Why are metals and metal alloys used?

Materials Science Overview - Metals and Alloys T oday on MSL-1 we highlight some of the materials science research being done in space. Metals and alloys are virtually everywhere in our daily lives. From them, we make aircraft engines, automobiles, bridges, buildings - even paper clips. Certain metals are appropriate for use in certain functions, while not suitable in others. B efore we can effectively use metals and alloys in products that we need, many questions must be answered through scientific investigation and experimentation: What makes some metals different from others? Why are some metals or alloys great for one application, but not so great for others? How do we know which metal or alloy to use in which situation? How can we learn beforehand , whether a metal or alloy is strong enough, flexible enough, or light enough for our needs? Can we design a metal or alloy to meet a particular need or set of circumstances? How do we build a metal part or piece of equipment so that its performance is maximized? What causes metal to break or lose strength?

Exploring Materials Engineering Metals and Alloys If there is a typical engineering material that is associated in the public's mind with modern engineering practice, it is structural steel . This versatile construction material has several characteristics, or properties, that we consider metallic : (1) It is strong and can be readily formed into practical shapes. (2) Its extensive, permanent derformability, or ductility , is an important asset in permitting small amounts of yielding to sudden and severe loads. Many Californians have been able to observe moderate earthquake activity that leaves windows (of relatively brittle glass) cracked while steel support framing still functions normally. (3) A freshly cut steel surface has a characteristic metallic luster, and (4) a steel bar shares a fundamental characteristic with other metals: it is a good conductor of electrical current. Although structural steel is an especially common example of metals for engineering, a little thought produces numerous others [such as gold, platinum, lead and tin]. An alloy is a metal composed of more than one element. Engineering alloys include the cast-irons and steels, aluminum alloys, magnesium alloys, titanium alloys, nickel alloys, zinc alloys and copper alloys. For example, brass is an alloy of copper and zinc.

Metals and Alloys TEMPUS Large Isothermal Furnace Coarsening in Solid-Liquid Mixtures TEMPUS Everything floats in weightlessness, but making things float where you want them to float is a challenge. Germany is meeting that with TEMPUS , an electromagnetic levitation furnace that will melt samples without them touching the walls, thus rendering nearly perfect samples. ...more Large Isothermal Furnace The Large Isothermal Furnace developed by Ishikawajima-Harima Heavy Industries Co., Ltd., for the National Space Development Agency of Japan (NASDA). Japan's National Space Development Agency will be making its third flight in space. LIF heats and cools an entire sample, hence the name iso (same) thermal (temperature). Six experiments are to be conducted using the LIF. They are: Liquid Phase Sintering (LPS-2) :This process is used by industry to form very hard, dense solids, which are used in anything from cutting tools, to car transmission gears to radiation shields! The materials are made by fusing (sintering) metal or ceramic powders. Liquid phase sintering uses a special liquid, made from the material itself, to suspend the powders for fusing. However, gravity affects the dispersal of the powders suspended in the liquid, and causes the resulting solid to be less uniform. This experiment is designed to better understand this process and develop techniques that can be used to lower costs of production, and create even better solids using LPS. The history of physics has been marked by measurements of constants, numbers - like the speed of light in a vacuum or the value of pi - that anchor equations so we can get useful answers from other values that vary. Despite centuries of experience in mixing, molding, and casting metals, we still don't have several constants - called diffusion coefficients - for mixing certian sets of metals. In samples large enough to measure the diffusion, gravity can disturb the answer the results. Five LIF experiments will pursue these constants:

17. METALS & ALLOYS | Cost Of Corrosion and titanium alloys. The total 1998 consumption cost of the corrosionresistant metals and alloys is estimated at $7.7 billion. http://www.corrosioncost.com/methods/resistantalloys/

Corrosion-resistant alloys are used where corrosive conditions prohibit the use of carbon steels and protective coatings provide insufficient protection or are economically not feasible. Examples of these alloys include stainless steels, nickel-base alloys and titanium alloys. The total 1998 consumption cost of the corrosion-resistant metals and alloys is estimated at $7.7 billion. According to the U.S. Census Bureau statistics, a total of 2.5 million tons of raw stainless steel was sold in the United States in 1997. With an estimated cost of $2.20 per kg ($1 per pound) for raw stainless steel, a total annual (1997) production cost of $5.5 billion was estimated. It is assumed that all production is for U.S. domestic consumption. The total consumption of stainless steel also includes imports, which account for over 25 percent of the U.S. market. Thus, the total consumption of stainless steel can be estimated at $7.3 billion. CORROSION CONTROL METHODS Protective Coatings Corrosion Inhibitors Corrosion Control Services Where environments become particularly severe, nickel-base and titanium alloys are used. Nickel-base alloys are used extensively in the oil production and refinery and chemical process industries, where conditions are aggressive. Further, there is an increased use of these alloys in other industries, where high temperature and/or severe corrosive conditions exist. With the average price for nickel base alloys at $13 per kg in 1998, the total sales value in the United States was estimated at $285 million.
